54327225 ÷ 378 
The aim is to understand the frequency of 378 in 54327225.

Let's proceed to step 1:
5 divided by 378 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 378

Advancing to step 2:
The number 378 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 378

On to step 3:
The number 378 fits into 543 1 times, leaving a remainder of 165.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 378 from 543 to get 165.
Fetch the next digit (2) from the dividend, attach it to 165 and continue: 1652 / 378

On to step 4:
378 goes into 1652 4 times with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1512 from 1652, we get 140.
Take the next digit (7) from the dividend and append it to 140, then repeat: 1407 / 378

Moving on to step 5:
1407 divided by 378 is 3 with a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Subtract 1134 from 1407 to get 273.
Grab the next digit (2) from the dividend, add it to 273, then carry on: 2732 / 378

Let's proceed to step 6:
378 can be fit into 2732 7 times, resulting in a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 1437.0
Subtracting 2646 from 2732 leaves us with 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 378

On to step 7:
378 goes into 862 2 times with a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 14372.0
Subtract 756 from 862 to get 106.
Grab the next digit (5) from the dividend, add it to 106, then carry on: 1065 / 378

Let's proceed to step 8:
378 can be fit into 1065 2 times, resulting in a remainder of 309.
Put 2 as the next digit of the answer. 
Result so far: 143722.0
If we take 756 away from 1065, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 9:
When dividing 3090 by 378, we get 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 143722.8
Subtract 3024 from 3090 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
378 goes into 660 1 times with a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 143722.81
Subtract 378 from 660 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 11:
The number 378 fits into 2820 7 times, leaving a remainder of 174.
The next digit of our result is 7. 
Result so far: 143722.817
Subtract 2646 from 2820 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 12:
If we divide 1740 by 378, we get 4 and a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 143722.8174
Subtracting 1512 from 1740 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 13:
378 can be fit into 2280 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 143722.81746
If we take 2268 away from 2280, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
378 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 143722.81746
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 15:
If we divide 1200 by 378, we get 3 and a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 143722.8174603
If we take 1134 away from 1200, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 16:
660 divided by 378 is 1 with a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 143722.81746031
If we take 378 away from 660, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

The quotient of the division is 143722.81746031, and the remainder is 2.82e-07.
